What was the impact of the Children's behavior on the narrator?

The restraint and composure with which the children handled themselves in the moment of CRISIS boosted the morale of the narrator and SPURRED him onto action. He realized that if his children could exercise such remarkable self-control with the possibility of death LOOMING over their heads, then he as a grown man could also SHOW courage and determination under duress and take them to safety. It dawned on him that he somehow had to make it for them. He saw how his boys were cheerful and OPTIMISTIC and most importantly, how his little girl did not fret over her injuries and how his little boy was not afraid of death. Such resilience pushed him to take the reigns of their safety into his own hands and achieve what had seemed to be impossible.
